As to that foremost, rare, and hard - to - understand Dharma accomplished by the Buddha— only the Buddhas and the Buddha can exhaust the Real Mark of all dharmas. That is to say with regard to all dharmas: the suchness of the marks, the suchness of the nature, the suchness of the substance, the suchness of the power, the suchness of the function, the suchness of the causes , the suchness of the conditions, the suchness of the effects , the suchness of the retributions, and the suchness of the ultimate equality from beginning to end.
